Figure 14 Bivariate scatterplot showing the relationship between maxillary tooth count with maturity among 14 in A high-resolution growth series of Tyrannosaurus rex obtained from multiple lines of evidence

Figure 14 Bivariate scatterplot showing the relationship between maxillary tooth count with maturity among 14 specimens of Tyrannosaurus rex. Growth rank increases away from the origin (i.e., maturity increases to the right) and corresponds to growth stages for which maxillary tooth count was available for a given specimen; that is, the rank does not correspond to growth stage. Maxillary tooth rank corresponds to relative tooth count, where low ranks correspond to high tooth counts and low ranks correspond to high tooth counts. Full-size DOI: 10.7717/peerj.9192/fig-14
